Okay, is there a definitive way to check which version of firmware you have installed on the Airport Extreme? My status page shows 7.2, but the update utility just had me install 7.1.1 (downgrade???)... I had the non-gigabit version of the Airport but I returned it to BestBuy and got the gigabit version from the Apple Online store. I immediately started having issues with my airport disks, getting errors on both my PC and Mac, saying "unknown user, incorrect password, or login unavailable". Now this morning I see it wants to downgrade me to 7.1.1 from the 7.2 that came on the gigabit AEBS. I'm qutie sure my old AEBS was 7.1.1. Could 7.2 have been responsible for the Airport disk problems people have been seeing?
